SLIDE-RAIL B A EQ Specificationof Letters Patent.

Application filed June 14, 1919. Serial No. 304,312..

Toall whom it may concern Be it known that we, LOUIS DUssART and EDWARD- COLIN, citizens of the United States and theFrench Republic, respectively, both residing at Kincaid, in the countyof Christian and State'of Illinois, have invented certain new and useful Improvements in Slide- RailBraces, of Which the following is a specification, reference being had to the accompanying drawings. h V y This invention relates to slide rails such as are used to form extensions of tracks in mines. v V

In mining tunnels, more or less permanent tracks are laid leading from a position more or less'adj acent the breast of the work, upon which tracks the cars receiving the ore are disposed, o. Slidinglyengaged with these permanent rails are slide rails which,-as the cutting continues, are shifted relatlve to the permanent rails so as to extend, as it' were,

the permanent rails toward the breast or face. These sliding rails are not held firmly in position, and indeed are usually held upon the'last tie of the permanent'trackby a pair of spikes and by their engagement with the main or permanent rails of the track. As a consequence of this, these sliding rails will often be diverged from 'each other or converged toward eachother so that the slid ing track becomes either toowide or too narrow and the mine car gets off the track.

The thrust of this 'car' is often the cause of, the silding rails shifting laterally or being forced apart.

The object of this invention is to provide means for holding the outer ends of the slide rails from moving toward or away from each other, and as the inner ends of the slide rails are held by the spikes before referred to, it is obvious that the rails will be held in parallel position, that is in gage. A further object of the invention is to pro vide a brace which will engage the outer ends of the slide rails and hold them to' proper gage, and to provide a brace which, being formed in two parts, may be adjust able as to length, inasmuch as there is no standard width or gage for these slide rails or for the. tracks in different mines.

The inventionis illustrated 1n the accompanying drawings, where1n:

Figure 1 is a top plan View of a portion of a main track showing our invention applied tothe sliding rails thereof, the brace being partly in section;

Fig. 2 is an end elevation of the construction shown in Fig, 1; and

Fig. 3 is a section on the line 33 of Fig.1. a I

Referring tothese drawings, it will be seen that our device comprises a brace consisting of two sections 10 and 11. Each section comprises a head and a shank, which head 12 is formed with a slot 13, which has the fo m of a cross section of a slide rail. This slide rail has the form of an ordinary 7 track rail set on its side so that'the flanges extend vertically instead of horizontally.

One of the sections, as for instance the sectlon 11, has a hollow shank. The other section has a shank l4. ofsufliciently small size to be inserted in the hollow shank 15 of the section 11, and both of these shanks are perforated, as at 16, for thepassage of a locking pin 17. This locking pin is attached to one of the members 10 or 11 by means of acha-in 18'. J f k a The slide rails 19, as before remarked, are likethe main rails 20- of the track, but are disposed with their flanges extending vertically andwith the head of each slide rail disposed between the base and the head of a main rail (see-Fig. 3)., These slide rails are'held, in position by one or more spikes 21 so that they may be shiftedlongi tudinally from timejto time as desired. The slide rails 19 at one or both ends are formed with perforations 22 through the web, and pins 23 are provided connected to each head 12 by means of a chain 24:, which chains are adapted to be inserted in the perforations 22 to limit the outward move- Patented Oct. 7, 1919.

ment of the brace with relation to the slide 4 rails. v

Theuse of this device will be obvious from what has gone before. It is simply engaged with the outer ends of the slide rails 19 and held in place by the pins 23.

Thereafter the slide rails may be pulled out as much as desired and they will always be held in parallel relation. It will be seen that this brace also constitutes a stop limiting the movement of the cars in one direction upon the slide rails. The brace will,

7 of course, be made of iron or steel, and may be of any 1 desired size and expansible or contractible to any desired length. The device is very simple, can be readily applied, and prevents derailing of the cars and thus prevents the loss of time due to replacing the cars on the track.

Furthermore, this slide-rail brace, by pre venting the derailing of cars on the slide rails, eliminates danger of injury to operators incident to lifting the cars to replace them on the track, and the loss of time incident to such replacement.

We claim 1. In a mine track, the combination with main rails and slide rails disposed inward of the main rails and slidable thereon for longitudinal movement relative thereto, of

-a brace engaging the slide rails at their outer ends remote from the main rails and holding said slide rails from relative lateral movement, said brace being formed in two relatively adjustable sections.

2. A brace for the slide rails of mine tracks composed of two sections having sliding engagement with each other, of means for holding the sections in any longitudinally adjusted relation, each section at its end being formed with anfopening hav ing-"the same form as the cross section of V with relation to eachother.

4:. In a mine track, the combination with the main rails and slide rails disposed in ward of the main rails and having longiflopies of this patent may he obtained for tudinal movement relative thereto, of a brace for the outer ends of the slide rails, said brace having at its ends slots through which the outer ends of the slide rails are disposed, and means for preventing the brace from being disengaged from the slide rails.

5. In a mine track, the combination with the main rails and slide rails disposed inward of the main rails and; having longi' tudinal movement relative thereto, of a brace for the outer ends of the slide rails,

said brace having at its ends slots through which the slide rails are disposed, and pins flexibly connected to the brace, the slide rails being formed with perforations in which said pins may be disposed to thereby prevent the slipping of]? of the brace.

6. The combination with the main rails of a mine track, rails disposed inwardof the main rails and having channels in their upper faces, the inner Wall of each channel being coincident with the lateral face of the head of the main rail, means for holding the slide rails with their inner ends against the side faces of the main rails but,

permitting said slide rails to be longitudinally shifted, and members operatively detachably engaging those ends of the slide rails remote from the main'rails and hold-- rails from:

ing the'outer ends ofthe slide lateral movement.

In testimony whereof We hereunto atiixz our; signatures in the presence of two witnesses.
